UNITED TATES THOMAS HOLLIDAY, OF HUDDERSFIELD, ENGLAND.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 581,117, dated April20, 1897.

Application filed October 2 S, 1 89 5.

To aZZ whom, it may concern.-

Be it known that I, THOMAS HOLLIDAY, a

subject of the Queen of Great Britain, residing at Edgerton,Huddersfield, in the county of York, England, have invented certain newand useful Improvements in Gas-Burners; and I do hereby declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

' This invention relates to an improved process of and apparatus fordiluting gas rich in carbon with air atthe burner, and it is especiallyapplicable to mingling acetylene with air at the point of combustion.

My invention will be readily understood from the accompanying drawings,in which Figure 1 represents a vertical elevation, and Fig. 2 across-section, of my improved burner.

A represents the burner-column, screwing upon a suitable support B. Thecolumn A may be made adjustable upon the support B by turning thecolumn. The support B terminates in a small jet 0 below the opening D inthe column. The column again extends to the mixing-chamber E, the upperend of which connects with the burner F, preferably of the union-jettype. Air-0penings G pass through the column and into the interspaceabove the jet 0.

The operation is as follows: Gas under sufficient pressure passesthroughthe opening 0 and then through the opening D into themixing-chamber. The opening D, being larger than the opening 0, allowsfor the passage of air with the gas into the chamber E.

' The relative size of the openings 0 and D determines the proportion ofgas to air, which may also be varied by the adjustment of the column Aupon the support B. The openings in the burner F should be made ofsufficient size to allow the escape of the mingled air and gas withoutforcing them backward through the openings G.

semi No. 566,584. (a model.)

I am aware of the patent to Jones and Collins, No. 55,949, dated August7, 1866, and the patent to Averill, No. 141,415, dated August 5, 1873,and do not claim the structure there shown. These and similar structuresoperate by mingling the air and gas in a lower chamber and then passingthem in a mingled condition through a constricted orifice. By myapparatus the gas is jetted in a thin stream through a chamber, where byits passage it causes an influx of air, and then the jet, withoutbreaking up, passes into an upper chamber through a constricted orificein which the mingling of the air and gas is done. This can only be doneby an arrangement in which the gas-jet and the constricted orifice areproperly proportioned and close together, and by means of it an air andgas pressure is maintained in an upper chamber. By my apparatus, forinstance with a pressure of six inches in the gas-supply pipe to whichthe support is connected and a constricted orifice D of four times thediameter of the gas-jet O, a pressure of two inches of water can beattained in the upper mixing-chamber, a result impossible with any ofthe previous jets known to me.

' Vhat I claim as my invention, and desire to secure by Letters Patent,is

A gas-burner for mingling air with a gas rich in carbon, comprising asupport having a fine jet, a column having an opening to the airadjacent to the jet, a mixing-chamber, a constricted opening into themixing-chamber, above, close to and in line with the jet, but largerthan the jet, and a burner in the column above the mixingchamber,substantially as described.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

THOMAS HOLLIDAY.
